Hash Hashemian: Visionary leadership
As Dr. Hashem M. “Hash” Hashemian prepares to step into his term as President of the American Nuclear Society, he is clear that he wants to make the most of this unique moment.
A groundswell in public approval of nuclear is finding a home in growing governmental support that is backed by a tailwind of technological innovation. “Now is a good time to be in nuclear,” Hashemian said, as he explained the criticality of this moment and what he hoped to accomplish as president.
20th International Topical Meeting on Nuclear Reactor Thermal Hydraulics (NURETH-20)
With more than 30 years of experience in both academia and industrial research, Dr. Yang is a recognized expert in reactor thermal-hydraulics and nuclear safety, advanced fuel design and qualification, rod bundle CHF and multiphase flow measurements, subchannel analysis, CFD simulation, acoustic wave propagation, online Real-Time Transient Modeling (RTTM), and leak detection in multiphase flow pipelines. Dr. Yang began serving as Director at Columbia University’s Heat Transfer Research Facility (CU-HTRF) from 1993 to 2002. He served as senior exclusive advisor for Westinghouse/ABB/Toshiba group from 2002 to 2012. From 2012 to 2017, Dr. Yang was appointed as a professor and the Dean of the School of Nuclear Science and Technology at Xian Jiaotong University (XJTU) in China.

As the TPC Chair, Dr. Yang successfully organized the 1st and 2nd International Seminar on Subchannel Analysis-CHF and CFD (ISACC) in 2013 and 2015 respectively. In 2018, as the TPC Co-Chair, he helped to expand ISACC to IS-ReCTHA to include various topics on reactor core thermalhydraulics. In 2017, as TPC Chair, Dr. Yang successfully organized NURETH-17 with over 800 papers and 1,000 participants. Dr. Yang also organized/co-organized over 30 other international conferences and workshops, and he was the invited keynote speaker for several international conferences. In 2022, he was the General Co-Chair of NUTHOS-13 and Steer Committee Co-Chair for NURETH-19. Currently, he also serves as the General Co-Chair for three different international conferences: NURETH-20 (2023, Washington DC), NUTHOS-14 (2024, Vancouver), and ATH-2024 (Orlando, FL).
Dr. Yang was awarded NURETH Fellow (2019), the Excellent in Review Award (2021), and the highest technical achievement award from ANS THD, TAA (2022). He is the current Chair of ANS-THD (2022-2023).
